xChip Boards

xChips are a rapid electronics development ecosystem to help reduce development time and simplify making custom products as well as aiding learning. Without soldering, wiring, breadboarding, or hardware knowledge you can assemble a circuit in minutes, and concentrate on coding.

xChips are compatible with the platform you want to use and bridges are available for the most popular pltatforms; Raspberry Pi, Minnowboard, Beaglebone, Micro:bit, Pixhawk and 96 boards. Rather than bridging to Ardunio, we offer compatible cores for Arduino Uno, the CC01, and for Arduino Zero, the CC03.

xChips utilise I2C, and due to this bus architecture, unlimited expansion of circuits is possible. Limitations of I2C addresses have been negated by development multiplexers.

Because of its simple connection method, it is easy to build quickly - for prototyping and small product runs

xChips connect to each other using an xBus connector, available from RS 174-4977.

Some xChips need an xPDI connector (RS 174-4974) to connect to programming interfaces, such as the IP02 or IP03.

OC05 – Servo Driver xChip (PCA9685, BU33SD5)

This xChip is an output control module, based on the PCA9685 from NXP Semiconductors, which is an I²C-controlled Pulse Width Modulation or PWM controller with a built-in clock. This controller used as an interface to accurately drive up to 8 servo motors. The module accepts an input power source locally to drive the motors.

The OC05 xChip is a servo motor controller driver that uses the PCA9685 PWM controller as servo interface supported by a BU33SD5 regulator to drive and accurately control up to 8 servo motors on a single module and act as a system power supply. The module has 8 standard 2.54 mm (0.1”) servo headers, plus 1 standard 2.54 mm (0.1”) battery/BEC input header.
